UNITED STATES PATENT OFFICE.

WINDOW CONSTRUCTION.

Application filed February 15, 1923.

To all furbo/m, t may concern:

Be it known that I, HARRISON D. VIILSON,

a citizen of the United States, and a resident of the city of Chicago7 in the county of Cook land State of Illinois, have invented certain new .and useful Improvements in a Window Construction g' and I do hereby declare that the following is a full, clear, and exact description of the same7 reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specifica tion. y

It is an object fof the present invention to provide a metal construction for window frames and window sashes which shall be more inexpensively manufactured than such articles have been heretofore.

It is a further object of this invention to provide a metal stock material of such cross section that it may be used for any part of the window frame.

It is a further object of this invention to provide a metallic window sash adapted to co-operate with such a window frame.

It is a further object of this invention to provide a metallic weather strip adapted to co-operate with such window frames and sashes.

It is a further object of this invention to provide a ybearing for` windows of the pivoted type which shall prevent all noise and rattling in such windows.

It 1s a further object of this invention to provide a metallic window sash into which the window glass may be slidY and will be then surrounded by the sash so that the addition of a single closure member along the entrance side of the sash will completely enclose the glass.

It is a further object of this invention to provide such a window sash with a putty retaining means whereby a saving in putty is effected.

Other and further important objects of this invention will be apparent from the disclosures in the accompanying drawings and following specification.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown on the drawings:

The window has an upper sash 2() and` a lower sash 2l which are mounted in the window frame 2Q by a lazy tongs form of pivot support closely similar to that described in my Patent 1,1937101, granted August lst, 1916. The two upright members and the top cross piece ofthe window frame each have a cross section somewhat resembling the letter Z. The two upright members, however7 have a trough produced in the middle of the portion corresponding to the oblique part of the Z. This is well illustratcdv at the right hand part of Figure 4, where the-middle portion 23 of the upright member has a trough 24C projecting toward the right. The portion of this member nearest the'exterior of the building` has a flange 25 corresponding to the lower line of the letter Z and the portion next the interior has a wider flange 26 corresponding to the top part of the letter Z. The side of this flange next the middle of the window is turned inward, as shown at 27, to afford an edge against which the sash abuts.

Stock for making the upright part of the frame may be rolled in long lengths and cut olf to the desired size. By turning a. piece of the stock end for end the part corresponding to the left hand portion of Fig ure 4- is provided, wherein the same numbers designate the corresponding parts. Because of the reversal of the piece, these parts occur in a, different order making a section re sembliug` the letter S instead of the letter Z.

The bearing of these upright members against the wall of the building is afforded by angle irons, one arm 28 of which lies against the interior surface of the wall and the other arm 29 of which constitutes the facing of the edge of the wall towards the window. This facing does not extend across the whole of this edge, but the thickness of the wall `goes beyond the depth of the window frame. The flange meets the surface of the wall at SO and the arm 29 of the angle iron is secured to the flange 25 at this point. This joint may be made by brazing, electric welding, or in any other desired fashion.

The upper cross piece of the frame also co-operates with an angle iron which. however, is somewhat differently positioned. One arm of this angle iron, as shown at `3l in Figs. 1 to 3. is against the interior surface of the wall. The other arm 32 is against the top surface of the middle part 3B of the cross member. This middle part has no trough, but otherwise it is of like cross section. The inner edge of the top frame member merges into a channel 34, the two ends of which form miter joints with the corresponding parts 26 and 27 of the upright members. The exterior portion of the top frame member forms a channel 35, the inner wall 36 of which co-operates with the edge of the channel 34 to afford a pocket for the reception of the upper edge of the top sash. The outer wall 37 of the channel has its edge against the edge of the wall and so makes a good finish to the window frame. It forms miter joints with the parts i i of the uprights.

The lower member of the frame consists of a bar, the middle portion of which rests obliquely and extends horizontally across the window, as shown at 40. On the interior of the wall this member has connected to it an angle bar 41, one arm of which is secured by brazing, electric welding or in any other desired manner to the oblique portion /t-O, and the other arm of which rests against the interior surface of the building wall. The exterior *surface of the building wall is contacted by a flange 42 on the edge of the oblique portion 40. The wall is made with a shoulder to cooperate with this flange and from this shoulder outward the wall slplpes to provide the usual water shed or s1 The oblique portion is provided with a vertical portion 43 making miter joints with the portions 26 of the vertical members. A channel 44 is attached by its web 44a to the flange and extends transrcrsel y of the window to form a weather strip or seal for receiving the fold 5l. of the sash` The bottom and the two side members: of the sash for each pane are all made of stock of the same cross section. This includes a portion at right angles to the plane of the glass, as shown in Figs. l and 7. On the edge next to the inside of the window this stock is folded back upon itself to form a double-walled flange 5l, from the edge of which the stock turns through a right angle and then a second right angle to form a beariu(r member whose, edge i?, is separated. trom the `:glass by only the putty. The edge of the portion 50 nearest the outside of the wall is turned a 'ay from the glass and then folded back upon itself to form a double-\\'allef;l flange 5ft. The exterior wall of this flange continues parallel to the glass and then is turned inward to form a similar bearing edge for the exterior' surface of the glass. The 'two upright members of the sash are connected to the bottom member by miter joints. Before this connection is made, however, a put-ty receiving trough is passed lengthwise into each of the sash members. This trough is most clearly shown in Figure 10. Tt has a base and flaringsides 62.

In assembling the window the putty troduced into these troughs througl opening between the edges 5?) and ,i y opening is to accommodate the glass. fh the troughs have been filled with putt the desired depth, the glass is f: the top of the sash, causing the putty to lill the trough and to come out th `gli the space between the edges and an and the glass, as is shown at G3 in Figure 10.

The top member of the sash consists et' two pieces .(34 and which afford ing the glass in the same ray 53 and instead ofl heine' iu lane at rio'ht angles to tho e" ssN 1 s 1U t1 t. t?

other members of the sash, these pieces t3!- and G5 are turned into a plane paralle! tu the sash. as shown at GG and G7. Tl for receiving putty is in this cas. of a general U-shape in cross ser-tion filled with puttyv and introduced between the flanges G6 and GT and beingl compre for its passage between them. When it: is in the space between the members and G5 Ad' cent the glass, this member eixpai as shown in Figure into the saine forni as the other putty receiving members. The troughshaped member is then forced home so thi.

the putty is caused to eXude between they members 64e and 65 and the glass. as shown 12" at G3 in Figure f). This done by forni a closure strip into place between the Gangi 66 and 67. This strip is of a forni somewhat resembling the letter M and the central pcf'- tion 68 contacting with the 'fiat part 60 of the putty trough forces it into vthe illustrated position and so brings the putty into the pos sition described. The extreme members 69 and 70 of the Closure i'ziember contact with the anges 66 and 67. Bolts 8l are inserted throughtianges (S6 and 67 and all 'lour walls of the closure member and the insertion ot these bolts completes the 'fastening oi? the sash.

The lower' member ot lthe sashv tor the lower part ot the window is provided with an apron 82, as may be most readily seen in Figure 2, which, in the closed position ot the window, by contacting with the outer flange 42, upon the lower member oi the trame, makes a weathentight joint. Also this apron, being somewhatresilient. a' '.ts in holding the window against rattling. The lower member ot the sash on the upper window is provided with an angle iron S8, which co-operates with the double-walled flange 5 oit that member to Form a trough, which, in the closed position ot the window, receives the projecting` parts 66 and 6"? and the inclosure member on the upper edge of the lower sash, as may be best seen in Figure i.

Secured to the portion 50 of the upright member ot the sash foreach of the windows is a fixture or stirrup which carries a Vpivot 86 for receivingthe sleeves or eyes 8? that constitute the outer joint of the lazy tongs support furthe window. The links and cross members constituting` this lazy tongs correspond exactlyto the similar members in the `above-mentioned patent and need not here be described in detail. Slots 88 are provided in the portions ott the upright frame members for the reception of the moving ends of the lazy tongs members secured to the frame. The other ends of these lazy tongs members are pivoted to the 'frame as shown at 89.

ln order to better guide the sash in its motion, an additional-beariug is aliorded near the upper end oit each sash. For this bearing a strap 90 is provided which. as shown in Figure 6, is bolted. riveted or otherwise secured to the part 50 ot the upright portion ot the sash. The strap 90 has a portion 91 which is bent to be parallel to the frame and a portion 92 bent through a right angle to contactI with the sash. Near the upper end ot the portion 91 a pivot 93 is provided which projects into the trough 24.

The part of this pivot contained within the trough 2iis surrounded by a resilient shock-absorbing strap 95, the middle portion of which, as shown at 9G, is made practically circular to enclose'and tightly engage the pivot 93 and the two end portions of which, as shown at 97, are rounded to bear against the side walls ot the trough 24. The windows are adapted to swing upon the pivots 93, as shown in Figure 2. The windows may be swung upside down as shown in Figure 8; during such movement, the pivots 93 'sill slidedownwardly in the grooves The traine members 25 have secured to them adjacent to the tianges 2" a pair or angle irons best shown in Figures 7, one arm of which projects nirallel t. 1ange`2? and on the side thereof tower'vedge ofi" the window opening. Between arm of the angle iron 99 and the Vtir-.ng the double-walled iange 5l oit the s' ceived.k Mounted upon this arm ot iron 98 is a resilient strip oi bras metal 99, best shown in Figures Thisstrip has a general U-shapcr tion. The .arm of the b farthest f fiat an li windouv has its terminal edge close against the member oi? t. e ai 98 as shown at 190. The central pa strip is rounded, as shown at 10i. to

I ai'i'ord a resilient edge. The arm ot' the U-shaped section nearest the winflowhas a wide and shallow curvature, as shown at 102. to a'tford a resilient bearing against the double-walled iange 51. Preferably the end of this wall oi2 the strip 99 entends beyond the edoe 190 and lies atagainst the member or tne ai ffle iron )l 9S. Near the rounded edge lOl, the member of the angle iron 98 is perforated at intervals, as shown at 103, and depressions, as shown at 10%, are made in the metal to secure 4it in place.

In the application of this device to the iorm of window shown in Figure 7, two windows side `by side or two sashes mounted to independently Ypivot in one large window, are illustrated. The side members 23 of the window frames which come adjacent one another are of the form already described. For proper `spacing` apart, an ordinary channel iron 10G is used on the interior side of the frame, and an ordinary piece of strap iron 107 is used on the outside. Thus, no matter what the situation of rthe windows, the same rolled stock of standard cross section may be used for the upright members of the frame.

In Vthe operation ot the device, opening and closing the windows is as described in the above mentioned patent. The use of the several forms in assembling the device has been described in connection with the detailed description of the stri'icture. When the Window is closed, the double-walled flange 5l, forcing its way between the liange 27 and the Weather strip 99, presses the. portion 102 of this strip making it assume a flatter position. Thus a water-tight joint is afforded. The resilient nature of the pressure of this weather strip against the sash also assists in preventing rattling. Battling is further prevented by the resilient pressure of the arms 97 of the spring member against the trough 24. The Window is still further held resiliently in posilll) tion when closed by the apron 82. Thus, when the window is closed, no motion in any direction can take place without being resiliently resisted. All rattling is, thereiore, avoided.

I am aware that numerous details of construction may be varied through a wide range without departing from the spirit of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

l. In a weather strip support, a itat metallic member provided with a row ot per- -lorations, a resilienty metallic weather' strip member surrounding the edge oi said tiat member and extending along each tace thereof, said resilient metallic member having dents entering said perforations whereby said resilient member :is secured to said fiat member.

2. In a window construction, a window frame having a trough therein, a pivotally supported window sash, a projection from said sash into said slot, and resilient means surrounding said projection and contacting with the walls of said slot whereby rattling of the window is prevented.

3. In a window construction, a window frame provided with slot-shaped recesses, a sash provided with flanges adapted to enter said recesses, resilient weather strips mounted upon one wall of said recess and adapted to co-operate with said flanges to resiliently hold the window in place, upright troughs in said trame, a window sash having projections entering said upright troughs, and resilientV means surrounding each projection and co-operating with the walls ot its trough to resiliently hold the window in place, the lower edge of one of said window sashes having a resilient apron adapted to resiliently engage the bottom member of the window iframe whereby when the window is closed it is resiliently held in position from motion in all directions and rattling thereby prevented.

l. In combination, a window sash including members surrounding the edges of the glass, projections secured to said members, a window frame having troughs for receiving said projections, resilient members each including a cylindrical portion surrounding one ot said projections, and two wing portions, one contacting each wall of said trough, the ends ot said wing portions being curved away from said wall whereby motion ot the projection at right angles to the walls of the trough is resiliently prevented.

In a. window sash construction, integral metallic members surrounding the edge ot the glass upon each oit three sides, metallic members connecting said irst-named members across the fourth side and positioned one on each t'ace ot' the glass, the space between said metallic members being slightly greater than the thickness oi. the glass, and aI resilient trough-shaped metallic putty-receivmg member adapted to be introduced between said connecting members through said space, said resilient metallic` member assuming when so introduced a position straddling the edge ot the glass.

6. In a window trame, vertical side members, each member having a grooved portion in the plane of the window and a channel extending transversely to the window, and a weather strip associated with said channel.

7. In a window construction, a frame comprising vertical side members, each member having a central portion extending transversely ot' the window and an end portion parallel with the window, such end portion having an inwardly directed terminal flange, and a member secured to said portion in spaced relation to said ilange to provide a channel for receiving a port-ion of the window sash.

8. In a window frame, vertical side members, each member having a central portion extending transversely ot the window and an end portion parallel with the window, such end portion having inwardly directed parallel tianges to provide a channel-like groove, and aweather strip associating with one of said anges.

In testimony whereof I have hereunto subscribed my name.
